Abstract：5G commercial process has been started. The 5G core network architecture and key technologies have been basically determined. However, in order to better enable vertical industries, achieve faster service deployment and more efficient operation and maintenance, 5G core network still needs to be continuously optimized and evolved. The continuous evolution of the 5G core network will be realized in three aspects: deterministic network, intelligent network and agile network. The network slicing, edge computing and service-oriented architecture are also continuously optimized. For vertical industries, key technologies such as Non-Public Network (NPN), 5G Vertical Local Area Network (5G LAN), Time Sensitive Network (TSN), Network Data Analysis Function (NWDAF), and Network AI are introduced. These technologies will further promote the development of 5G core networks.
